Filed Sept. 4-, 1964, Ser. No.394,451 7 Claims. (Qt. 126-11d) My invention relates primarily todevices for burning gas for the purpose of heating enclosures such asdwelling rooms and is particularly concerned with a kit for adapting toadditional uses a Wall furnace of the sort shown in the copendingapplication of Gardner and Serrano, Serial No. 374,786 filed June 12,1964 for a Wall Heater.

In the mentioned application, there is provided a wall furnace having agas burner and a heat exchange surface connected to a vent flue andenclosed by a perforated grille and designed for installation betweenthe vertical studs in the wall of a dwelling. The gas pipe is brought into the bottom portion of the wall for supplying the burner and the ventflue extends upwardly between the studs and within the confines of thewall to a suitable point of discharge above the ceiling of the room.

While many installations of Wall furnaces are made in new houses duringthe course of construction and can ready be disposed largely between thewall studs with only a portion of the wall furnace protruding into theroom, there are other occasions in which it is desired to install a wallfurnace without interfering materially with the preexisting wallstructure.

It is therefore an object of this invention to provide a wall furnacekit particularly for adapting a wall furnace for installation within aroom against the face of an existing wall.

Another object of the invention is to provide a wall furnace kit whichcan readily adapt a wall furnace for installation on the face of a wallrather than between the studs of the wall.

Another object of the invention is to provide a wall furnace kit whichwill afford a neat and finished appearance for an installation of a wallfurnace situated entirely within a room against the wall.

Another object of the invention is to provide a wall furnacekit in whicha safe installation can be made in an existing room.

Another object of the invention is to provide a wall furnace kit whichcan readily be installed by an ordinary workman without any particularinstruction or experience and without the necessity of utilizing specialtools or involved techniques.

A further object of the invention is to provide a wall furnace kit whichis simple and economical to manufacture with the customary toolsutilized in the manufacture of wall furnaces.

A further object of the invention is in general to provide an improvedwall furnace kit.

Other objects together with the foregoing are attained in the embodimentof the invention described in the accompanying description andillustrated in the accompanying drawings, in which:

FIGURE 1 is a front elevation of a wall furnace kit constructed inaccordance with the invention, certain portions of the furnace grillebeing omitted and parts of the figure being shown in cross section on atransverse vertical plane;

FIGURE 2 is a cross section, the planes of which are indicated by thelines 2-2 of FIGURE 1;

FIGURE 3 is a cross section, the plane of which is indicated by the line33 of FIGURE 1;

FiGURE 4 is a cross section, the plane of which is indicated by the line44 of FIGURE 1;

plane of section being indicated by the line 5-5 of FIG- URE 3; and

FIGURE 6 is a cross section to an enlarged scale, the plane of sectionbeing indicated by the line 6-6 of FIG- URE 1.

While the wall furnace kit of the invention can readily be adapted towall furnaces of different sorts, it is particularly utilized inconnection with the wall furnace disclosed in the above-identifiedapplication. This furnace includes a central heat exchange section 6below which a gas burner 7 is disposed and which leads at its upward endinto a generally flattened elliptical discharge outlet 8 The furnacealso includes (FIGURE 6) a pair of outstanding securing lugs 9 and 11having out-turned portions 12 and 13 for the reception of thecustomarily provided grille 16.

Pursuant to the present arrangement, there is afforded a kit so that thefurnace can be situated in a room having a floor 17, a boundary wall 18inclusive of upright studs 19, and a finish coat 21 such as plaster, andalso having a ceiling 22 usually of plaster supported on ceiling joists23 and 24 customarily spaced apart a predetermined distance. The kitincludes a pair of upright side supports 25 and 27, each of which isformed of sheet metal and in transverse cross section is approximatelyC-shaped. Each shape is made up of a side panel 28, an inturned forwardflange 29 and an inturned rearward flange 31. Also, at the bottom eachof the side supports has an inturned foot flange 32 adapted to rest onthe floor 17.

At its upper end, each of the side supports 26 and 27 has an inturnedtop panel 33 merging with a vertically extending fastening tab 34depending from the top panel 33. In order that the side supports can besuitably fastened in place, each of the rear flanges 31 is atappropriate intervals provided with apertures 36 for the reception ofscrews or nails 37 driven into the wall 18 and intended to engage thestuds 19 therein. In this fashion, the side supports are secured firmlyin position, resting on the floor and secured to the wall at asubstantially standard distance apart so that they extend parallel toeach other and vertically.

Extending between the side supports is a header 38 of the sameconstruction disclosed in the above-identified application and includinga horizontal or transverse planar portion 39 encompassing a flanged,flattened elliptical opening 41 for the reception of the outlet 3 of thefurnace and to position a flue 42 of standard sort which extendsupwardly through the ceiling 22 to an appropriate discharge point. Theheader 38 at either end is provided with a downturned flange 43positioned so as to overlap the lower portion of the adjacent fasteningtab 34. Sheet metal fasteners 44 are passed through correspondingopenings in the flange 43 and in the tabs 34 and not only serve tosupport the header on the side supports, but also assist in aligning andpositioning the side supports relative to each other.

With this much of the kit, the furnace can be installed. Preferably, abottom or floor plate 51 is rested on the floor 1). This has at itsopposite ends downturned flanges 52 abutting the inturned flanges 32 andusually abutting the side walls of the upright supports as well as thefront and rear flanges 2? and 31. It is not essential that the bottomplate 51 be secured by fastenings in position since it is well locatedotherwise. This is partially accomplished by the positioning of thefurnace. The outlet opening is inserted into and telescoped with theflue 42 by being passed through the opening 41 in the header while thelower portion of the furnace extends into the room. The lower portion isthen moved into position between the upright side supports until thebottom portion of the furnace rests on the bottom plate 51. The tabs 9and 11 are brought into position immediately overlying the inturnedflanges 29 at their lower portions. Then sheet metal screws or othercomparable fastenings 56 are passed through the tabs 12 and 13 into theflanges, so that all of the parts in this area of the structure aresecurely held in place and fastened together.

To afford a better appearance and better support, as well as fireprotection, for the upper portion of the structure, the kit is extendedto include an upright jacket 61. This is a sheet metal structure whichincludes a front panel 62 and a pair of side panels 63 and 6d. At itslower end the front panel 62 extends across the header 38 and can infact rest thereon. At their lower ends the side panels 63 and 64 extendacross and depend slightly below the top panels 33 on the upright sidesupports. The depending tabs 34 and the side panels 65 and 6d of thejacket are secured together in appropriate position by sheet metalfastening 66 passing through appropriate apertures in the adjacentmembers. While this fastening. is ordinarily sufficient, it is alsopossible to afford apertures in and fastenings through inturned flanges67 and 68 at the rear portion of the jacket.

The jacket is made sufiiciently long or high so that when installed itcan be passed through an opening in the ceiling 22 and will extendupwardly into the attic space thereabove to any selected extent. Sincethere is usually adequate room for this purpose, the jacket 61 can bemade a standard length for practically every instal 13.- tion. It willextend only slightly into the attic in high ceilinged rooms, but willextend materially into the attic in low ceilinged rooms. Of course, ifnecessary the jacket can be cut off on the particular job, but it ispreferred to avoid any such extra Work, if possible.

Since the ceiling aperture is usually not made with great accuracy andsince it is desired to provide a further support and finish to theinstallation, there is provided a ceiling plate 71. This is generally ahorizontal sheet metal member having an appropriate edge finish "72 forgood appearance and good abutment with the ceiling 22. The plate 71 isformed to provide an opening to receive the jacket 61 and also to afforda front plate 73 upstanding vertically along the interior forward edgeof the ceiling plate. The plate 71 is also formed with a pair ofupstanding sides plates 74 and 76 and spaced to engage closely theceiling joists 23 and 24.

The ceiling plate is moved through the ceiling opening around the jacket61 and is stopped with the plate abutting the ceiling. In this positionthe side walls 74 and 7e are preferably secured to the ceiling joists 23and 24 by fastenings 77 of any suitable sort. Additionally, sheet metalscrews 78 are passed through openings in the forward wall and speciallypierced openings in the jacket 61 so that all of the parts are wellsecured together. The jacket is supported by the ceiling joists, as wellas its other fastenings, and the entire installation is firmly made andis pleasing in appearance. Also, a well protected air space is providedaround the flue pipe 42 for substantially its entire length.

When so much of the installation has been made, there is afforded asuitable basis for the mounting of the standard front grille 6, This ishooked over the inwardly and downwardly inclined projection 81 along thefront of the header after the flanges at the rear of the grille havebeen introduced behind the tabs 12 and 13 of the fastenings 9 and 11.With the positioning of the grille, the installation is completed andthe general aspect is of a regular and permanent installation of thewall furnace despite the fact that none of the furnace is actually inthe wall, but rather stands out into the room.
